Highly doubt it, the 12Gb on the Pixel will surely perform better. Hardware is hardware, there's no magic to overcome such a huge difference of available RAM.
How absurd!
More RAM consumes more battery. In what scenario are you going to utilize all that much memory? Load of open apps in the background? Its A12 equivalent performance won't be able to time sharing more than a few apps, yet all the memory banks need energy to refresh all the time. You must consider the balance for a device running off battery.
Apple has its 'Unified Memory' design; CPU and GPU share the same memory pool and thus no memory copy/moving between them and that's the magic you don't believe exists. Note this is Unified Memory, not Shared memory everybody uses for integrated GPU which needs to preallocate memory for GPU operation, decreasing real memory useful for CPU and needing memory copy to and fro.
I saw the magic myself when open and process the same 50MB of a raw file from mirrorless camera on iPad Pro (2nd generation) vs from SSD on my 2017 iMac (48GB of RAM); the speed difference in loading the image is more than astonishing .
Looking it in other way. With my iPad Pro, I can swipe through JPEG image embedded in raw files for preview almost as fast as swiping through normal JPEG image; on the iMac, the image needs time to gradually fade in to its full glory.
The magic has been again proved by the M1 powered Mac lines. In most scenarios, such as opening app, opening more tabs in browser, opening large office data file, 8GB on base model M1 outperforms 16GB or more on Intel based MacBook Pro.
Except superior core design, it has super super fast storage for backing store for app/data swapping. It's almost like you got hundreds of GB of 2nd tier of RAM.
You can't benchmark smarts with traditional benchmarks. Look at how dumb Siri still is on latest silicon.
Silly as it is we don't argue; the same that you can't argue it's purposely dumbed down for privacy and it relies on on-device AI instead of server cluster.
How about Cinematic video (portrait mode in 1080p 30fps), ProRaw (stack of raw pixel data of a photo with computational add-on) and ProRes (for movie industry) ? No other smartphone can do any of these.
